PureVision Contact Lenses
PureVision contact lenses contain an enhanced optical design that corrects spherical aberration. Left untreated, light rays are refracted at different angles through the eye, which can result in a loss in visual quality. With Purevision, you not only correct your vision while you wear them, you actually restore the shape of your eye for optimal vision and prevention vision loss. And actually with these lenses, the longer you wear them the better. As a disposable monthly lens, you can sleep in them and wear them for up to a month without irritation. Then toss them for a new pair and enjoy supreme comfort and vision for another month.
